| 主权项 | 1. A colourless inkjet ink composition comprising at least 30% by weight of monofunctional acrylate monomer based on the total weight of the ink and at least 3% by weight of a photoinitiator based on the total weight of the ink, wherein the photoinitiator comprises an a-hydroxy ketone photoinitiator and wherein the ink comprises 0 to 6% by weight of acyl phosphine photoinitiator based on the total weight of the ink, wherein the colourless inkjet ink comprises 3 to 40% by weight of N-vinyl amide and/or N-acryloyl amine based on the total weight of the ink, and wherein the a-hydroxy ketone photoinitiator is present in an amount of 25 to 100% by weight based on the total weight of photoinitiator, wherein the monofunctional acrylate monomer is selected from the group consisting of phenoxyethyl acrylate, cyclic TMP formal acrylate, isobornyl acrylate, tetrahydrofurfuryl acrylate, dicyclopentenyl oxyethyl acrylate and mixtures thereof, and wherein the n-acyloyl amine is n-acryloylmorpholine. | ||
